Abstract: Disclosed is a structure of a single fishing line guide of a fishing rod, including: a frame provided with a centering hole formed therethrough for guiding a fishing line; and a supporter extended from the frame and bent such that a bent portion is formed between the supporter and the frame and contacts the fishing rod to fixedly support the frame, wherein the bent portion is protruded from a supporting area and contacts the fishing rod, thereby supporting the frame.

Abstract: Disclosed herein is a center ring structure for a fishing rod, a plurality of center rings being provided on the fishing rod for guiding a fishing line. Each of these center rings is defined in a frame so as to penetrate through, and the frame comprises a surface contact recess formed at a lower side of the frame for allowing the frame to come into partial contact with an outer peripheral surface of the fishing rod or with a mount ring slidably fitted around the fishing rod, and a guiding groove formed along an outer periphery of the frame for winding a thread around the frame and the fishing rod so as to fix them relative to each other. The present invention can simplify the center ring structure by allowing the center ring itself to be affixed to the fishing rod, and can allow adjustment of the distance between the center ring and the fishing rod through variation in shape and size of a center ring aperture formed in the frame.

Abstract: This invention proposes a fishing line guide ring including unevenness continuously formed in the inner circumference of the fishing line guide ring so as to reduce an area where a fishing line contacts the inner circumference of the fishing line guide ring when the fishing line meets with resistance generated at various angles by fish biting the fishing line, so that deformation of the fishing line due to frictional heat of the fishing line is minimized, the surface area of the fishing line guide ring is maximized to easily emit heat generated by the fishing line guide ring and the fishing line. The fishing line guide includes embossed surfaces or recesses and protrusions continuously formed in the respective inner circumferences of the fishing line guide rings to reduce the frictional area between the fishing line and the fishing line guide rings and to increase the surface area of the inner circumferences of the fishing line guide rings.
